Bentley and John A Peterson,v Decoraln'Iowa) a I ff satiat on November 1c, 1938, Serial Ne. 239,874 i a 120mm. 'I'his i'nvention' relates to an implementtripping device and has for theprimary-object theprovision of a device of this character which is in the .of "the implement drawn .by said tractor, so that .1 the operator of thetractor, may at any time desired actuate the tripmechanism from a seated I position on. the tractor, through the use of the claimed. v 4 For a complete understanding of our invention, reference is to be had to the following descripfoot, leavingthe "hands freefffor the-control of the tractor and lwhi'chiir'icludes'means for automatically separating should the implement become disconnected from the tractor obviating any possibility of breaking the attachment and the latter may be convenientlyrearranged for operating thepowerliftof the tractorwhen desired.

With these and other objects injview, the in; V

vention consists in certain novel features of construction, combinationandarrangement of parts to be hereinafter more fully described and tion and accompanyingdrawings, in which Figure '1 is a fragmentary side elevation, partly in section, showing a portion of attractor and an f implement drawnthereby and equipped withan attachment constructed I in I accordance with the in section showing a portion of the tractor with I present invention. Y I I Figure 2 is a'fra'gme'ntary side elevation, partly the attachment arrangedfor the operation of the ing the automatic power lift offlthe tractor.

. Figure 3 is an exploded perspective view showattachment.

Referring in detail to the drawings, the numeral' 5 indicates a portion of a well knowntype Y, of tractor, the draw hal being indicated by y the.

? character 6 and-connected :to a'draw bar 'I of .a cultivating implement ilfof conventional, construction and which includes a trip mechanism 9 having an actuatingleVer 10. The hitch' between the tractor and. cultivating implement is usually of the type which is automatically releasable'f should the implement engage with an obstruction so as to uncouple from the tractor to prevent breakage or damage eitherfto the implementor thetractor.

I 'operator of the tractor from a seated position use of the foot. 1 v

release forming a part of the p t u dl of the upper 'andlower edges of 'the'yoke The presentinvention.consists of a foot pedal Hv 'pivotally mounted on the tractor, as shown at "I 2,:and has connected thereto a flexible element" l 3, which extends, rearw'ardly from: the v tractor,and-is"suitably'secured to the lever 1x of thetrip mechanism 9. Mounted on the tractor for the draw barv 6 thereof through the use of suitable clamps I4 is a flexible-tubexor housing 'I 5 through which the flexible element I3 extends housing rrz. a r The flexible element l3 ispreferably constructed in sections, one of which is connected to I the foot pedal and the other tothe lever lil of the trip mechanism 9. The adjacentjends'15 1 of the sections are detachably connected by a coupler, 1 6 which will "automatically release the section'sshould the implement andtractor'separate ,to' obviate" any possibility of breaking the flexible element l3-j0r, any of the other therpresentinvention: r

"'Ihe coupler I6 3 consists of a substantially-U shaped yoke I1 whichlhas one-of the sections of v the flexible. element connected thereto'an'dis provided with a slot 18 to receive the arm portions I9- 01? a spring 'clip 20. The arm portions l9 havetheir free end portions arranged in divergingrelation, The arm portions are connected by a coiled' portion 2| providing necessary tension tofthe arm-portions which tends to spread; said arm portions and also to provide an eye to which the other; section of the ,flexible element I3 is connected. The arm portions l9 are contracted and insertedthrough the slot l8 and allowedto expandso that thediverging free 35 end .portions of said arm" portions extend outz-tions I9 fitting in theiyoke as described Willhave 40 -suflicient bearing on said yoke'as' to withstand :ordinary pull on the flexible element for, the

' actuation of the trip mechanism 9- by thefoot pedal; However, should separation of the implement 'oc'curjfrom the tractor, the spring arms 45 ['l9 will pull out of the yoke and thereby obviates possibility, of breaking the flexible element l3 s or any of the other parts of the present invention. .;Also thecoupler I6 affordsmeans whereby v t I the sections of the flexible element may "be sep- Withrthe, present invention installed on the.. arate whendetaching the implementqfrom th tractor and'the'implement itis possible for the" tractor manually as a'person may readily con- -tractthe arm portions I9 of the. spring clip 20 and withdraw said arms from theiyoke l1, leaving f oneof'the. sections of the flexible element atand'is-guided in "its movement by said tube or 10 parts of I tached to the implement while the other section of the flexible element remains on thetractor; The attachmentmay, at any time, be employed for operating the power life mechanism of the tractor and, generally indicated by the character 22 and which includes a hand lever 23. The

flexible element it is extended about the rear axle construction of the tractor, as clearly shown in Figure 2, and is connected to the lever 23 by a clip 2% sothat the operator ofthe tractor. 7 through the use of the foot on the pedal 22 may move the lever 23 and bring about oper:

ation of the power lift mechanism. It is to be understood that the clamps Mare removed from the draw bar 6 and attached to'the rear axle housing of the tractor when adapting] the g attachment to the power lift mechanism.'

Through the useoi the-"clips it will; bear:- parent that the present attachment can be readily attached onto the tractor through the use of bolts already on saidhtr'actoro I 'It is believed that the foregoing description, when taken in connection with the drawings will fullyset forth the construction and advantages of this invention to thoseaskilled in the art'to which such a device relates, so that further detailed descriptionwill not be required.
